pub struct Operator<const C1: char, const C2: char = '\0', const C3: char = '\0', const C4: char = '\0'>;
Expand description
Operators made from up to four ASCII punctuation characters. Unused characters default to \0
.
Custom operators can be defined with the crate::operator!
macro. All but the last character are
Spacing::Joint
. Attention must be payed when operators have the same prefix, the shorter
ones need to be tried first.

The actual parsing function that must be implemented. This mutates the
tokens
iterator directly. It should not be called from user code except for implementing
parsers itself and then only when the rules below are followed. Read moreSource§impl<const C1: char, const C2: char, const C3: char, const C4: char> PartialEq for Operator<C1, C2, C3, C4>

fn parse( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, ) -> Result<Self, Error>
This is the user facing API to parse grammatical entities. Calls a
parser()

transaction. Commits changes on success and returns the parsed value. Read moreSource§fn parse_all(

fn parse_all( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, ) -> Result<Self, Error>
Exhaustive parsing within a transaction. This is a convenience method that implies a
EndOfStream
at the end. Thus it will error if parsing is not exhaustive. Read moreSource§fn parse_with<T>(
